Takayasu's arteritis(TA) is a nonspecific areritis of unknown etiology affecting segmentally the aorta and its main branches, which result in stenosis, occlusion or aneurysm of involved arteries. The clinical manifestations present with a variety of symptoms such as headache, dyspnea on exertion, pain and weakness of extremities, pulse deficit, and hypertension according to involves arteries. Usually it can be managed by medical or surgical treatment, and recently by percutaneous transluminal balloon angioplasty. The type III classified by Lupi-Herrena and associates is the most frequent variety of TA. However the case of type III involving both subclavin arteries and both renal arteries has rarely been reported. We experienced a case of TA involving both subcalvian arteries, and both renal arteries presented with paroxysmal hypertension and right flank pain, in which the stenosis of both subclavian arteries were managed by percutaneous transluminal balloon angioplasty and the stenosis and occlusion of both renal arteries were successfully managed by aorto-renal bypass surgery with autogenous right iliac artery and synthetic vessel(Gortex). The patient was discharged uneventfully.

OBJECTIVES: To assess the relationship between ST segment elevation during exercise testing and coronary artery disease. METHODS: Treadmill exercise electrocardiography and coronary angiography were performed in 137 patients with angina with no Q waves. The J point elevation of > 0.03mV(0.3mm) measured from baseline, the elevation of ST segment at 80msec. from J point(ST80) measured larger in lead V1than in aV1, or both the elevation of ST segment at J point and at ST80 developed earlier than or concomitantly with ST depression were considered as abnormal responses. RESULTS: 1) There was no clinical significance of ST elevation in lead aV1. 2) Exercise-induced ST elevation in lead V1occurred in 29 of 137 patients with angina. 3) Abnormal St elevation in V1was detected in 26 of 86 patients with coronary artery disease, for a specificity of 98%. The patients with left anterior descending coronary artery or left main coronary artery stenosis were observed in 3 of 5(60%) patients with single-vessel disease, in 7 of 9(79%) with two-vessel disease, and in 9 of 10(90%) with three-vessel disease. 4) The standard ST depression yielded a specificity of 55% in the patients with isolated or predominant ST depression in inferior leads(II. III, and aVF) and of 81% in the patients with isolated or predominat ST depressin in precordial leads(p<0.001). 5) Abnormal exercise-induced ST elevation in V1was detected in 13 of 39(33%) patients with isolated or predominat ST depression in inferior leads and yielded a specificity of 94% for coronary artery disease. CONCLUSION: Abnormal ST segment elevation in V1may increase the specificity in isolated or predominat ST segment depression in inferior leads and may predict left anterior descending or left main coronary artery disease.

OBJECTIVES: The aim of this study was to explore the changes of bronchoscopic features according to epidemiologic change of lung cancer. METHODS: We performed a retrospective review of the clinical characteristics of 1,139 lung cancer patient who underwent bronchoscopy at Kosin University Hospital from January 2000 to December 2010. RESULTS: The age of patients increased significantly during the last decade (P < 0.001). The most common histological type was adenocarcinoma (38.1%), followed by squamous carcinoma (35.7%) and small cell carcinoma (15.3%). There was an increasing incidence of adenocarcinoma over the time (P < 0.001). Bronchoscopic feature were divided into two classes; central type, peripheral type. The peripheral type was predominant (62.3%). The proportion of peripheral type has been increased in process of time (49.7% vs. 63.7% vs. 73.7%; P < 0.01). Among the major histopathologic type of lung cancer, adenocarcinoma (81.3%) and unclassifiable non-small-cell lung cancer (73.4%), small cell carcinoma (56.9%) were associated with preferential occurrence of peripheral type. Squamous cell carcinoma of the lung more often arised in central type (59%). However, the proportion of peripheral squamous cell carcinoma has been increased. On the subgroup analysis, the median survival time of peripheral type with adenocarcinoma and small cell carcinoma were longer than central type (P < 0.05). CONCLUSIONS: The age of the lung cancer patients at diagnosis was getting older. The most frequent histopathologic type was adenocarcinoma. The proportion of peripheral type lung cancer gradually increased over the time. The survival time of peripheral type lung cancer was longer than central type.

Solitary extramedullary plasmacytoma (EMP) is a plasma cell neoplasm without bone marrow involvement. EMPs are rare in the gastrointestinal (GI) tract. We report two cases of primary EMP, one in the transverse colon and the other in the stomach. In the first case, a mass on the transverse colon was found on colonoscopy. The patient underwent left hemicolectomy and has been followed-up for 3 years without recurrence postoperatively. The latter case had several masses in the stomach. The patient underwent bypass surgery and has received supportive care for 1 month. Histopathologic specimens of both the cases showed a monoclonal lambda chain EMP. Subsequent investigations included a bone marrow biopsy, serum IgA, IgG, IgM and serum protein electrophoresis, and the results were negative for multiple myeloma in both the cases. Solitary EMP in the GI tract can be mistaken for colon cancer or stomach cancer on endoscopy; therefore, a sufficient number of biopsy specimens can help diagnose solitary EMPs. Surgical resection alone or with radiation therapy in cases with positive surgical margin is currently the only treatment for solitary EMP in the GI tract. Further study is necessary to determine disease prognosis and to investigate other treatment methods.

Sustemic arterialization of the lung without sequestration is the rarest from of congenital anomalous systemic arterial supply to the lung, where an anomalous systemic artery arising from aorta supplies a normal unsequestrated segment of the lung. The non-sequestrated lung parenchyma which is supplied by an aberrant artery, has no parenchyma or bronchial abnormalities, and there is a normal connection with the bronchial trees. The symptoms of this disease varies. In most patients, it is often asymptomatic, but symptoms including dyspnea, hemoptysis, and central nervous system complications are possible. Here, we report a case of systemic arterialization of the lung without sequestration, which confirmed by angiography, with a review of the literature.

OBJECTIVES: With the rapid increase in the prevalence of diabetes, the age groups of diabetic patients are becoming diversified. This study will examine the degree of obesity, insulin resistance, and insulin secretion ability among patients first diagnosed with diabetes according to age and gender. METHODS: The subjects of this study included 616 patients who were first diagnosed with diabetes during a routine physical examination. This sample was obtained from a total of 28,075 adults aged 19 years and older who received the examination among 33,829 participants in the Korea National Health & Nutrition Examination Survey (KNHANES) from 2007–2010. The subjects were categorized by age into young age (age: 19 – 39 years), middle age (age: 40 – 59 years), and old age (age: 60 years and older). The degree of obesity was categorized according to body mass index (BMI) into normal weight (BMI: 18.5 ~ 22.9), overweight (BMI: 23 ~ 24.9), and obesity (BMI: 25 or above). Insulin resistance was evaluated by homeostatic model assessment of insulin resistance (HOMA-IR). RESULTS: It was found that 14.1% (n = 87) of a total of 616 subjects (324 men, 292 women) were in the young age group, 43.8% (n = 270) were in the middle age group, and 42.1% (n = 259) were in the old age group. In addition, 83.3% of men that were overweight or obesity were in the young age group, while 79.2% and 60.5% were in the middle age and old age groups, respectively. A total of 82.2% of women that were overweight or obesity were in the young age group, while 79.5% and 77% were in the middle age and old age groups, respectively. For men, the more obesity they were in all age groups, the higher their HOMA-IR. For women, the more obesity they were in the young age and middle age groups, the higher their HOMA-IR; however, women in the old age group showed the highest HOMA-IR when they were of normal weight. CONCLUSION: Among diabetic patients first diagnosed with the disease in Korea, the youth population had the highest obesity rate. Insulin resistance increases as an individual's weight increases among those patients who are first diagnosed with diabetes; the only exception noted is for elderly women.

OBJECTIVES: Ultrasound-guided fine-needle aspiration (FNA) is routinely used in the evaluation of thyroid nodules. However, it has several pitfalls, as has been noted in nondiagnostic and indeterminate cases. This study aims to investigate the value of BRAF(V600E) mutation co-testing in FNA cytology. METHOD: A total of 310 patients underwent BRAF(V600E) mutation co-testing in FNA cytology on thyroid nodules between June 2013 and June 2014. Of the 310 patients, 69 patients who had undergone a surgery for thyroid nodules were included in this study. The presence of the BRAF(V600E) mutation was determined by allele-specific polymerase chain reaction amplification of exon 15 of the BRAF gene. RESULTS: Of 69 cases, 33 (47.8%) were BRAF(V600E) mutation positive. The BRAF(V600E) mutation was not significantly associated with high-risk features such as tumor size, lymph node metastasis, and pathological stage. The respective diagnostic performance of FNA (P = 0.02), BRAF(V600E) mutation (P = 0.03), and ultrasonographic (P = 0.00) findings was statistically significant. The sensitivity, specificity and positive predictive value of FNA was 64.9%, 83.3%, and 94.8%. The sensitivity, specificity and positive predictive value of BRAF(V600E) mutation was 56.1%, 91.7%, and 96.9% and the US features was 91.2%, 91.7%, and 98.1% respectively. However, sensitivity of FNA with BRAF(V600E) mutation (77.2%) was lower than FNA with US (92.9%) and combination all together (92.9%). CONCLUSION: In this study, we found that US features were the most useful in preoperative differential diagnosis of thyroid nodules. BRAF(V600E) mutation co-testing in FNA cytology was also useful for diagnosis of thyroid tumors.

Consumer perception of processed food and restaurant food's nutrient labelling was surveyed. The subjects of this survey consisted of 1,507 parents, whose ages were 20-59 years old. The ratio of the respondents that have known nutrition labelling on processed foods was 89.8% and the ratio of whom have checked the nutrition labelling at their point of purchase was 72.3%. The nutrients which were considered important for nutrition labelling were fat (57.1%), calorie (56.3%) and sodium (49.0%). Also nutrient which were able to be recognized at a glance by the subjects were in the order of trans fat (62.1%), cholesterol (26.9%), calorie (23.9%) and sodium (21.0%). If restaurant menu's nutrient labelling be enacted, the answer rate that the menu's nutrition labelling may affect their menu choice is 90.6% of the respondents. Besides of the Fastfoods that are enforcement, restaurants of that customers want the menu to be labeled were 'pizza and chicken restaurants'. Nutrients that customers preferred to be labelled were calorie (62.0%), fat (60.3%) and sodium (50.9%).

This study was performed to analyse the tendency of the self-care studies, to investigate the variables related to self-care, which could be applied for the data establishing the theory of self-care. to accomplish the objectives of this study, the researchers analyzed 83 studies, available that contained the area of self-care, which was published in local and foreign areas between 1981 and Feb. 1997. The findings of this study are as follows: 1) Studies published in Korea were about twice more than foreign studies. According to the statistics, the number of studies in this study tended to increase year by year. Between 1991 and 1995 were most. Analysis on the subject of this studies showed, that they were most dealt with chronic diseases an adults. 2) The theoretical definition of self-care were most referred to Orem's self-care. For the main concept of studies, self care performance was the most. 3) The correlational study was most often used design and experimental study is tended to increase. The questionnaires were the most often used data collection method. There was lots of different variable measuring technique to evaluate main concepts. 4) In the results of analysis on the propositions related to the self-care performance, a client's education, social support, self-efficacy, and level of knowledge as a causal variable were found. Also, the physiological index improved and quality of life were fond to be significant effective variables.
